# Calls to TrueConf Server via SIP/H.323
# Connecting to a conference
To make a call from a hardware or software SIP/H.323 endpoint (including TrueConf Group or TrueConf Videobar) to a conference hosted on TrueConf Server, use a call string in one of the following formats:
00<Conference_ID>@<server>
00<Conference_ID>@<server>:<port>
where:
<Conference_ID>
— conference ID<server>
— the server domain name or IP address<port>
— the connection port (used if the port is different from standard5060
for SIP and1720
for H.323).
For example:
001949195144@video.company.com
001949195144@video.company.com:1730
To join a PIN-protected conference from an SIP endpoint, it is necessary to add PIN, separated by a comma after the conference ID in the call string:
00<conf_id>,pin@<trueconf_server>:<port>
# Call to a TrueConf Server user
To make a call from the endpoint to a user registered on TrueConf Server use one of the following formats:
<TrueConf_ID>@<server>
<TrueConf_ID>@<server>:<port>
where:
<TrueConf_ID>
— user TrueConf ID<server>
— IP address or domain name of the server where the call should be routed<port>
— the connection port (used if the port is different from standard5060
for SIP and1720
for H.323).
For example:
james78@video.company.com
james78@video.company.com:5070
# Additional features
Additionally, to make a call via SIP, you can explicitly specify the protocol name (UDP is used by default):
00<conf_id>,pin@<trueconf_server>:<port>;transport=<protocol>
Some H.323 endpoints like Cisco also support call strings with double hashes ##
. In this case TrueConf users and conferences can be called in this way:
<trueconf_server>##00<user>
<trueconf_server>##00<conf_id>
